Add optional component after the installation

Hi

Lets say we have installed istio in our K8s cluester.
Later we decide to add some additional components, for example, Jaegar. Can we just enable it?
It seems we have to re-install the whole istio again?

Thanks

Hmm – strangely, the docs don’t seem to make it clear. I’ve pinged a developer and will update here when I find out more info.

You can just reapply the new generated yaml that has jaeger, in which case k8s will only apply the difference.

Great! That’s what I was hoping.

So, @walkerline, you can just re-run the Helm installation with the new options. It won’t actually re-install everything; it will essentially just apply the differences.

Hope that helps!
